as this cherry-picking is kinda getting out of control, i propose the
following upgrade to the branching process:

- initial situation: 5.6.2 (previous lts release) is done and we want to
  release 5.8.0
- right after the last forward merges 5.6=>5.7=>5.8 before finishing
  branching 5.8.0 (that is *now*), we already create 5.6.3
- this appears obviously premature, as we just released 5.6.2, and the
  final downmerge from 5.6 to 5.6.3 is months away
- however, this gives us a place to integrate all critical lts fixes
  which we can forward-merge to 5.8.0
- weird twist: after 5.8.0 gets released and 5.6.3 is forward-merged to
  5.6, the branch can be temporarily closed again, until it is
  re-activated for the actual 5.6.3 release (or again temporarily for
  the 5.8.1 release)

the 5.6.3 branch would be hard-branched right away and owned by RM (i.e,
staging is restricted).
developers need to decide between 5.6 and 5.6.3 based on whether they
are targeting 5.8 or 5.8.0 when merged up.
